Portland State | News | PSU Students and Alumni to Participate in Community Service Project at Lewis Elementary Spent yesterday morning at Lewis Elementary with a group of Portland State University students who were helping us with a number of projects. At Lewis we have a very large amount of cyclone fence that surrounds our playground and ball fields. One of our PTA members had the idea of having students paint flowers and other designs on wooden discs, and then hang them on the fence. This was accomplished and the PSU group helped us hang them. They also worked in our outdoor center cleaning up yard debris, and rebuilding our fish pond.
